Andrew Palumbo commented on MAHOUT-1853:
----------------------------------------
T-digest is still in mahout-math.. I believe it is still shipped to the backend
in spark-dependency-reduced.jar. Its been a while since we've upgraded the
versions though.. not sure if any new versions have been released.
